code: def vsprint(expr, **settings):
      r"""Function for displaying expressions generated in the
      sympy.physics vector package.
  
      Returns the output of vprint() as a string.
  
      Parameters
      ==========
  
      expr : valid SymPy object
          SymPy expression to print
      settings : args
          Same as the settings accepted by SymPy's sstr().
  
      Examples
      ========
  
      >>> from sympy.physics.vector import vsprint, dynamicsymbols
      >>> u1, u2 = dynamicsymbols('u1 u2')
      >>> u2d = dynamicsymbols('u2', level=1)
      >>> print("%s = %s" % (u1, u2 + u2d))
      u1(t) = u2(t) + Derivative(u2(t), t)
      >>> print("%s = %s" % (vsprint(u1), vsprint(u2 + u2d)))
      u1 = u2 + u2'
